Abstract
An air bag assembly for an inflatable passenger vehicle restraint system comprises an inflatable air bag, a thrust neutral inflator for generating pressure gas and a reaction canister. The inflator has a cylindrical casing with a plurality of holes on opposite sides for discharging the gas to inflate the air bag. The reaction canister houses the inflator and has a part-cylindrical bottom wall terminating in upstanding side walls which operatively connect the inflator to the air bag. A plurality of aspiration holes are formed in the reaction canister side walls. A part-cylindrical baffle is mounted in the canister between the inflator and the bottom wall and has an outlet to direct gas discharged from the inflator away from the walls and to the air bag. Ambient air is aspirated through the aspirator holes upon gas delivery from the inflator discharge ports to augment the volume of gas delivered to the air bag. The aspirator holes also serve as pressure relief vents for the air bag.
